Laboratory Findings

Blood tests that may be done include:Website: [1]

Quantitative serum HCG

  • Human chorionic gonadotropin (HCG or b-HCG) is the most common tumour marker test used to diagnose GTD.
  • HCG is a very sensitive test for diagnosing most gestational trophoblastic tumours. HCG is usually measured in the blood, but it can also be measured in the urine.
  • HCG levels are much higher in women with complete hydatidiform moles and gestational choriocarcinoma compared to HCG levels in women with a normal pregnancy.
  • With partial moles, the HCG level is higher than normal, but it is not as high as with other types of GTD.
  • With placental site tumours, the HCG level may be slightly higher than normal, but it is not considered a good marker for this type of tumour.
  • An HCG test can help find GTD after pregnancy or miscarriage as this hormone should not be present in the blood or urine soon afterward.

Human placental lactogen (hPL)

  • Human placental lactogen (hPL) is a tumour marker that may be used to follow women with placental site trophoblastic tumours. High hPL levels are found in women with some types of GTD.
